Ok, this is not good style but it might get you what you want. Assuming your times are strings and you are confident that plain string comparison would work for you, you could do something like this: timesteps = ncfile.variables['time'] dates_to_skip = set(['June 23th', 'May 28th', 'April 1st']) filtered_timesteps =...

You can use a Regular Expression: regexp_substr('Hazel/Green==F123==Brown','(==F.+?==)') extracts '==F123==', now trim the =: ltrim(rtrim(regexp_substr('Hazel/Green==F123==Brown','(==F.+?==)'), '='), '=') If Oracle supported lookahead/lookbehind this would be easier... Edit: Base on @ErkanHaspulat's query you don't need LTRIM/RTRIM as you can specify to return only the first capture group (I always forget about that). But...

inet_addr() returns an in_addr_t, not an u_long. struct sockaddr_in's sin_addr is a struct in_addr, which holds an in_addr_t s_addr. This should do the trick: static struct sockaddr_in remote_server; remote_server.sin_addr.s_addr = inet_addr(remote_servername); ...

Instead of this byte[] buffersend = new byte[client.ReceiveBufferSize]; buffersend = GetBytes("00010002000B0300010004C380"); int bytesSend = nwStream.Read(buffersend, 0, client.ReceiveBufferSize); nwStream.Write(buffersend, 0, bytesSend); I think you just want this. byte[] buffersend = GetBytes("00010002000B0300010004C380"); nwStream.Write(buffersend, 0, buffersend.Length); There is no need to new up an array just to replace it with the results of...

Well, bin_prot is just a serialization protocol, and doesn't depend on whatever you're using for a transport layer. Basically, to serialize a value to string, you can use Binable.to_string function (or Binable.to_bigstring). It accepts a packed module. For example, to serialize a set of ints, do the following: let str...

Can it be applied to asynchronous client that can talk to one single server? And could it be a good choice? REQ/REP is not recommended for traffic going over the Internet. The socket can potentially get stuck in a bad state. The DEALER/REP is for a dealer client talking...

I found the solution for this problem, and even though I read the docs front to back and back to front, I had not seen it. The key is XPUB_VERBOSE. Add this line to after the backend initialisation and everything works fine backend.setsockopt(zmq.XPUB_VERBOSE, True) Here's an extract from the official...

You are getting this output because you are overwriting the keys in your array. You would need to save to another array (aka not 2-dimensional): <?php $tbl = "TranslationsMain"; $conn = new mysqli($servername, $username, $password, $dbname); if($conn->connect_error){ die("Connection failed: " . $conn->connect_error); } $sql = "SELECT * FROM " ....

Disagree with Galik. Better not to use strcat, strncat, or anything but the intended output buffer. TCP is knda fun. You never really know how much data you are going to get, but you will get it or an error. This will read up to MAX bytes at a time....

The client doesn't get to cause arbitrary events to fire on the socket. It is always a message event. Using the same client, try this server code in your connection handler: socket.on('message', function(data) { // data === "pressed", since that's what the client sent console.log("Pressed!"); socket.close(); }); ...

InputStream input = client.getInputStream(); BufferedReader in = new BufferedReader(new InputStreamReader(input)); Your problem is here. You can't use multiple inputs on a socket when one or more of them is buffered. The buffered input stream/reader will read-ahead and 'steal' data from the other stream. You need to change your protocol so...

Assuming you've got your server side things setup, you can use Square's Socket Rocket to implement the client side https://github.com/square/SocketRocket If you're using socket.io at the backend, there are plenty of iOS libraries available for those as well. SIOSocket is one such library....

You want to return json object in response, so it's required to set json type in response header. As given here public function select(){ $data['query'] = $this->users->select(); $this->output ->set_content_type('application/json') ->set_output(json_encode($data['query'])); } It is required to encode part as below for insert part. so you can use this generated url to...

The simple solution is to ignore the generic parameter when adding the Promise to the dictionary. This can easily be done by either inheritance or interfaces, depending on your needs (for example, Task<T> inherits from Task). Unlike Java, you can't simply use Promise<?> like you're trying to. For example: public...

We should probably change that to propagate the exception, but it would be a behavior change so we'd probably have to do it in 4.2 only, unless we make it an option. Actually, after further review; this can't be accommodated - you have to handle the exception via the connection...

I Assumed that you are using SQL this a generic query for your question: SQLCommand cmd = new SQLCommand(); cmd = "SELECT DEPT_ID FROM PERSONNEL_TEMP.DEPARTMENT WHERE DEPARTMENT_NAME= '" + combobox1.Text + "'"; here is what I recommend SQLCommand cmd = new SQLCommand(); cmd = "SELECT DEPT_ID FROM PERSONNEL_TEMP.DEPARTMENT WHERE DEPARTMENT_NAME=...

This question seems not specific to sockets, but to global variables in general. If you need to create a global variable (a socket, in this case) which must be accessible by multiple compilation units: You define the global variable in one single compilation unit (i.e. one cpp file) You declare...

You may have to define your own function.Here is an example I just tested, hope it is helpful to you(BTW: It is not advisable to implement such kind of functions in mysql. Maybe it is better to let the application servers to compute it instead of mysql :)). DELIMITER $$...

Not sure what you're trying to do with the NULL there, but basically you if you want to find a capital that contains the name of the country, the usage of the like operator is definitely in order. Just slap a couple of wildcards (%) around it, and you should...

It is because you aren't ending the value attribute, so your selected option becomes <option value="optionvalueselected" -- 'optionvalue' being the value of your selected option, and 'selected' being the attribute you want to set, but won't be set because you never ended value The following should work: <select name="course_id" id="course_id">...

You shouldn't be trying to set anything like that using jQuery when using knockout - instead, do it all on the viewmodel. Your <select> options are bound to your issuingCountries observableArray, and the value selected is bound to your IssuingcountrySelected observable. To select an option automatically, just set the property...

Answering your last question: no. Because: If client is behind NAT, and the gateway (with NAT) has more than one IP, every connection can be seen by you as connection from different IP. Another problem is when few different clients that are behind the same NAT will connect with your...

What I think is to Save Mat using FileStorage class using JNI. The following code can be used to save Mat as File Storage FileStorage storage("image.xml", FileStorage::WRITE); storage << "img" << mat; storage.release(); Then send the file using Socket and then retrive Mat back from File. FileStorage fs("image.xml", FileStorage::READ); Mat...

Here is working demo just a basic filter to apply filter9 on how many li elements to show https://jsfiddle.net/xd2482f6/6/ Instead of pasting all your code which you can get from the JS fiddler i will just add in changes made. <select id="filter9" > <option value="-1" > all</option> <option value="1"> 1</option>...

In your sql condition may be wrong i think, i modified that sql. select p.* FROM products p JOIN strings s ON p.title = s.id and s.language_en = "Product name" you can execute and see the result. Thank you....

The issue is in DownloadYP.py - You do not have the files - C:\\rrr\japan\limit.txt I would suggest creating a dummy file in the above directory with that name, and try running the script again. Also, on a side note - You are mixing the os path separaters from unix and...

Redis would probably be fastest, especially if you don't need a durability guarantee - most of the game can be played out using Redis' in-memory datastore, which is probably gonna be faster than writing to any disk in the world. Perhaps periodically, you can write the "entire game" to disk....

I have temporarily hosted a FB app on pythonanywhere for free and it worked like a charm. In case you plan to use Django, the version they offer usually lags behind. In that case, I'd higly recommend using Openshift, by RedHat....

Will the first call to send() return an ECONNRESET? Not unless it blocks for long enough for the peer to detect the incoming packet for the broken connection and return an RST. Most of the time, send will just buffer the data and return. will the next call to...

could you make your server log for heartbeats? and also post heartbeats to the clients on the socket? if so, have a monitor check for the server heartbeats and restart the server application if the heartbeats exceed the threshold value. also, check for heartbeats on the client and reestablish connection...

You would do this with a group by and having. You really provide no information about your data structure, but the basic idea is: select ip.item from design ip where ip.property in ('wheel', 'red', 'tire') group by ip.item having count(distinct ip.property) = 3; ...

Are the C functions recvfrom and sendto mutually exclusive? No. They can both be executed by different threads at the same time. sendto() doesn't wait for recvfrom() to read the data. It would place the data into the socket's buffer and return. Multiple sendto() may block for the previous...

Here is an example to do that in a vectorized way. You shall note that and and or are not appropriate for a vector of booleans, use & and | instead. import pandas as pd import numpy as np s = pd.Series(np.random.randn(600), index=pd.date_range('1990-01-01', periods=600, freq='M')) Out[76]: 1990-01-31 -0.7594 1990-02-28 -0.1311...
